Default 2008 LS3 Sensor Pinouts

I am using an aftermarket ECU on an LS3 and need some help with sensor pin outs.

I need:

Cam
Crank
MAP
Oil Press
DBW TB
DBW Pedal

Thanks.

I can help with the MAP:

LS3:
Pin 1 - 5 volts - gray
Pin 2 - Ground (low reference) - orange/black
Pin 3 - Signal to PCM - light green

now if someone just happened to have the LS1 version pinout, I'd be very happy (need to rewire my setup without burning my car down )

Thank you very much.

I have found the LS1 pinouts through various sources, including, IIRC, on this forum when I did a search. I didn't really log where it was because I am not focused on the earlier stuff, but you should be able to find it relatively easily.

Anybody else have any of the other ones?
